Trying to add an Event handler to a scheduled task in ColdFusion11.
I'm supposed to write a component that implements CFIDE.scheduler.ITaskEventHandler and "Specify a dot-delimited CFC path under webroot, for example a.b.server (without the CFC extension)"
I tried to put my component under
ColdFusion11/cfusion/wwwroot
ColdFusion11/cfusion/wwwroot/CFIDE
ColdFusion11/cfusion/wwwroot/CFIDE/scheduler
the Apache webroot
some virtual host webroot
I tried to add some dot notation (?) like CFIDE.scheduler.myEventHandler...
I don't understand if there is some more configuration at server level to understand.
I don't see any error in logs, the scheduler editor just refuse to save an EventHandler he cannot find, with the error
An error occured scheduling the task.
Invalid eventhandler.
Error: Eventhandler myEventHandler could not be found
Any help appreciated
The correct way seems to put the component in ColdFusion11/cfusion/wwwroot/myEventHandler.cfc, set the path as myEventHandler and implement in the component "CFIDE.scheduler.ITaskEventHandler"

Anybody else failing to open snapshots once they upgraded their VirtualBox from v5 to v6? Snapshots that were opening just fine are now failing for me with this error ...
HGCM#0: Bad auto mount point size: 0x5
[ver=3 pass=final] (VERR_SSM_DATA_UNIT_FORMAT_CHANGED).
Result Code: E_FAIL (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}
Some very old snapshots are able to open; but most new ones and ALL the ones I save now using VirtualBox 6 are failing to open. Same error above.
My host is Windows10 and the saved VMs are Ubuntu18 guests.
Disclaimer: It should not be an excepted solution as your saved state will be lost.
As I don't have any sensitive data in the saved state. I have discarded the saved state and it works fine for my case.
EDIT: in some cases it looks like if you take a snapshot using the saved state, and then discard the saved state you might be able to recover back to where your saved state was
Steps
Right Click on the OS
Select Discard Saved State... in the context menu.
Screenshot
Host OS: Windows 10, Guest OS: Ubuntu 18.04, on Virtual Box 6.0.0
I have resolved this problem by installing Oracle_VM_VirtualBox_Extension_Pack-6.0.4.vbox-extpack for my VirtualBox-6.0.4-128413-Win

I have a windows c++ application which runs under the normal (non-admin) user. I want that no user should be able to close/stop/terminate this application by any means.
Is there any active directory group policy available to achieve this or I need to do some programming for the same
The only way I know is that your app will launch run 2 or more background processes that check every few ms that your app and the other backgrounds are running, if not it re-launches them.This makes it very had or impossible to terminate your app manually.
You application might need to save its state to disk , if it needs to re-launch to the same stat is was when destroyed
you can also disable the close button or whatever can terminate your application. Also disable the taskmanager so users cannot kill your application
There is a technique called hooking which will allow injection of your code into Windows DLL's, altering certain behaviours performed by the operating system.
This would prevent the operating system killing these proccesses using the core DLL's.
There is a downside to this method though as it may flag up as a virus on anti-rootkit systems as this is a technique often used to prevent the user from killing an infection.

I am looking for a way to monitor and alert when a webjob fails. Is there any tools(Apart from cloudmonix and Newrelic) that can support this?
If you're using the WebJobs SDK, you might take a look at the new ErrorTrigger binding that was recently added (details here). It allows you to define a job function that will automatically be triggered when errors reach a certain threshold. Here's an example function that will be called whenever 10 errors occur within a 30 minute sliding window (throttled at a maximum of 1 notification per hour):
public static void ErrorMonitor(
[ErrorTrigger("0:30:00", 10, Throttle = "1:00:00")] TraceFilter filter,
TextWriter log)
{
// Access error details and send an email/SMS, etc.
// log last 5 detailed errors to the Dashboard
log.WriteLine(filter.GetDetailedMessage(5));
}
See the Error Monitoring wiki page for more information.

I am coding on Putty (in C++ for what it's worth) and I am currently encountering an error that gives me a really long stack trace. Apparently, the trace is so long that Putty won't let me scroll to the very top where it originated (where I typed "make"). Is there any way around this (except by obviously fixing the error)?
There are two ways.
Change the Window buffer size. Open Putty, load the connection (don't double-click or hit open), click on Window on the left panel and increase the Lines of scrollback to something like 3000 (I think the default is 200).
Same way, load the connection, and then on the left panel under Session you will have the sub-category logging where you can set a file where the entire session history will be recorded.
To increase the lines of scrollback, before you make a putty connection, click on the category Window and increase the lines of scrollback to 10000 or 20000 as may suit you.

I reffered many links to change IP address using C/C++. But I found that its only changing the setting temporary (untill the next reboot) and Once the system is rebooted , the all settings are gone.
I referred below links to achieve it.
Qt: Setting the IP
Set IP address using SIOCSIFADDR ioctl
etc. but ended up with temporary settings (remains untill the next reboot)
Is there any way to change the settings permanently through C/C++ ?????
Please direct me to the right path.
At startup Linux uses some configuration file to assign IP-address to an interface. Each distribution has its own file dedicated for that purpose. You should consult your distribution Wiki on the topic of how to set an IP-address at startup.
In general it is an administrative task (i.e. should not be configured dynamically via some custom program), but if you really want to do it in your C/C++ program, then you should parse the network configuration file and place there the address you want to assign at startup.
